Strap for Master Grand Tourbillon Diamond Bracelet

The Jaeger-LeCoultre Master Tourbillon 1663314 (Q1663314) is a pinnacle of Swiss watchmaking from Le Sentier. This reference within the Master family features a classically escapement tourbillon visible on the dial, elevating the collection's sober aesthetic. The 43 mm white gold 18K case delivers a cold, sidereal luminosity, while the in-house caliber 978 manufacture movement compensates gravity effects through a vertical-axis tourbillon rotating every 60 seconds. With polished and satin-finished surfaces, sapphire caseback, and a 20 mm lug width, this watch embodies technical expertise and functional complexity rather than decorative complication.
